How to redirect the visitor after the contact page: 


Open Contact.php and go to line 473 - 475 and change the line:

$link = ‘index.php?option=com_contact&task=view&contact_id=’. $contact[0]->id .’&Itemid=’. $Itemid; 
mosRedirect( $link, _THANK_MESSAGE ) 

replace that code with the URL for the contact Thank-you page as defined as follows:

$link = sefRelToAbs( 'index.php?option=com_contact&task=view&contact_id='. $contact[0]->id .'&Itemid='. $Itemid );
mosRedirect( 'index.php?option=com_content&task=view&id=28&Itemid=102' );

Create thankyou page and menu item for ID, change this in the code to redirect to the item ID - remove menu item

So this is a comparison chart (at least in my opinion) of 3 major joomla template/extension providers.  When I'm less caught up in work I'll try adding to this article.  But here's some lazy stats:

Thought I'd put this error in here and how I fixed it. Basically because firstly I don't want to have to create an account on someone else's forum just to post my answer and secondly because my solution is a "cowboy fix" rather than the other intelligent solutions on the web.

The issue was that I was building my first Joomla 1.5 component and getting the below error if I put in a menu:

Warning: implode() [function.implode]: Invalid arguments passed in /home/.../public_html/includes/router.php on line 325

Where "..." is the path on your server.

Having trouble ordering your frontpage articles? After re-ordering articles wondering where it was taking the order it puts the articles in the front page (or landing page) was confusing me. The quick answer is that it is within the menu manager > main menu > menu item section of your Joomla! Admin Panel.

Certain Advanced Parameters in your Menu Item called "Home" must be set correctly for the article ordering you set in your Front Page Manager to take effect.

If you are in the administration panel and you are editing your weblinks and you come across this error:

"404 - An error has occurred.

• Check that they're in the right section and category
